4 Claims.

This invention relates to a universally adjustable mounting or support for indicators such as machinists dial indicators.

An object of the present invention is to provide a simple and efiicient mounting or support for an indicator adapted for attachment to the in dicator by means of the lug formed on the back face of the indicator casing.

Another object of the invention is to provide an adjustable indicator mounting for this purpose which will permit angular adjustments of the indicator about the axis of its axially movable spindle while the indicator is supported from its lug on the casing.

A feature that enables the above objects to be accomplished is that a bracket attached to the lug in fixed position thereto is provided with a sleeve coaxially but loosely surrounding the spindle sleeve of the indicator, an adjustable arm being angularly adjustably attached to the outer cylindrical surface of this sleeve.

With the above and other objects in view the invention may include thefeatures of construction and operation set forth in the following specification and illustrated in the accompanying drawing.

In the accompanying drawing annexed hereto and forming a part of this specification, I have shown the invention embodied in an adjustable support for a dial indicator having a post or rod attached thereto for attachment to a suitable base, but it will be understood that the invention can be otherwise embodied and that the drawing is not to be construed as defining or limiting the scope of the invention, the claims appended to this specification being relied upon for that purpose.

In the drawing:

Figure 1 is a side elevation of a complete indicator support made in accordance with the present invention.

Fig. 2 is an elevation of the adjustable support or mounting taken at a right angle from the view shown in Fig, 1, and

Fig. 3 is a detail sectional view showing part of the bracket for supporting the indicator.

In the above mentioned drawing, there has been shown but one embodiment of the invention which is now deemed preferable, but it is to be understood that changes and modifications may be made within the scope of the appended claims Without departing from the spirit of the invention.

Briefly, and in its preferred aspect, the invention may include the following principal parts in 2 addition to a conventionalor standard form of indicator: a bracket adapted to be secured at one end to the lug outstanding centrally from the back face of the indicator casing and having a sleeve at its opposite end fitting loosely but coaxially around the indicator spindle sleeve, and an adjustable arm or bracket fitting the sleeve on the bracket.

Referring more in detail to the figures of the drawing, the dial indicator it has on its back casing an outstanding lug [2 formed integrally thereon. Secured to this lug I2 is a bracket l4 preferably detachably but fixedly secured to the lug and having a sleeve It loosely fitting about the spindle stem I8 of the indicator I I]. The outside surface of this sleeve [6 on the bracket It is carefully finished to cylindrical form and is positioned concentrically of the indicator spindle stem [8.

Secured to this sleeve l6 as by being clamped to its cylindrical surface is an arm 20 the opposite end of which is pivotally secured to the upper end of a suitable post or rod 22 which may be secured in any manner to a base (not shown). The pivot 24 connecting the arm 20 to the post 22 has its axis preferably horizontal as shown in the figures of the drawing While the axis of the sleeve IE on the bracket I4 about which the dial indicator It) may be angularly adjusted is at right angles thereto.

By means of these two pivotal connections the indicator Hi may be adjusted to any angular position. Also, as the sleeve IS on the bracket surrounding the indicator spindle stem l8 does not contact the other portions of the indicator, clamping of the bracket Hi to the indicator does not compress the indicator stem l8 and interfere with the free action of the indicator spindle 26 and other mechanism of the indicator.

I claim:

1. An adjustable mounting for a dial indicator having an outstanding lug formed on its casing and a stem through which the indicator spindle extends comprising a bracket attached to said lug at one end, a sleeve formed on said bracket through which said indicator stem extends, an arm rotatably connected at one end to said sleeve, and a support pivotally connected to said arm at its opposite end.

2. An adjustable mounting for a dial indicator having an outstanding lug formed on its casing and a stem through which the indicator spindle extends comprising a bracket attached to said lug at one end, a sleeve formed on said bracket through which said indicator stem extends, an arm rotatably connected at one end to said sleeve, and a support pivotally connected to said arm at its opposite end, the axes of said connections being normal to each other, whereby said indicator may be moved to position its spindle in any direction.

3. An adjustable mounting for a dial indicator having an outstanding lug formed on its casing and a stem through which the indicator spindle extends comprising a bracket attached to said lug at one end, a sleeve formed on said bracket at its opposite end through which said indicator stem extends, an arm rotatably connected at one end to said sleeve, and a support pivotally connected to said arm at itsopposite end, theaxes of said connections being normal to each other.

4. A universally adjustable mounting for a dial indicator having a central outstanding lug formed on its casing and a stem through which the in- 20 dicator spindle extends comprising a bracket rigidly attached to said lug at one end, a sleeve formed on said bracket at its opposite end through which said indicator stem freely extends, an arcuate arm rotatably connected at one end to said sleeve, and a support pivotally connected to said arm at its opposite end, the axes of said connections being normal to each other.
